Give Your Deck a Second Life

Deck Extensions & Re-Decking in North Dakota

Save the Frame. Upgrade the Rest.

The Smart Way to Improve Your Deck

If your deck’s surface is worn but the structure is still solid, re-decking might be the perfect option. At Alliance Deck Builders of North Dakota, we inspect your existing frame and—if it passes structural checks—we can upgrade the surface with new composite or wood decking. We also extend decks outward, add stairs, upgrade railings, and create more usable space without a full rebuild. It’s a cost-effective way to modernize your backyard while improving safety and curb appeal.

More Room. Less Waste.

Benefits of Deck Extensions & Re-Decking

Tearing out a full deck isn’t always necessary. If your existing framing is solid and code-compliant, we can save time and cost by building on what’s already there. Re-decking lets you swap out old boards for fresh composite or cedar, while extensions expand your usable space for seating, grilling, or hot tubs. We match finishes, update railings, and add new stairs or landings as needed—all while keeping the bones of your deck intact.

Can Your Deck Be Reused?

Before we take on any re-decking project, we do a full structural assessment of your current framing. That means checking joists, footings, ledger connections, and overall spacing. If the structure passes inspection, we’ll offer a detailed plan for re-surfacing and upgrades. If not, we’ll explain exactly what needs to be replaced—and why. Our goal is always to reuse when it’s safe, and rebuild when it’s not. You’ll never be left guessing.

Seamless Additions That Match Your Style

Whether you want to add a dining area, a grill nook, or just a bit more legroom, we build deck extensions that blend perfectly with your existing structure. We match materials, railing styles, stair layout, and color so your addition looks like it was always part of the plan. From basic bump-outs to multi-level expansions, we tailor every build to your needs and space.

Faster, Smarter, More Affordable

Why Re-Decking Makes Sense

Re-decking saves money, shortens construction timelines, and reduces material waste. By keeping the foundation of your deck intact, we focus your budget on high-impact upgrades like composite surfacing, rail systems, and custom finishes. This approach is ideal for decks under 20 years old with structurally sound framing. Plus, it minimizes disruption to your yard and schedule—most re-decking projects are completed in a fraction of the time of a full rebuild.
